This is the Revolution Design Racing Products Ultra Cap Catcher. The RDRP Ultra Cap Catcher is a simple but genius idea that safely mounts speed controller capacitors such as found on Novak or LRP ESC's. Instead of having an unsightly capacitor attached using cable ties or large amounts of double-sided tape, the capacitor is held in place using a single layer of tape and can be mounted near the controller or wherever it fits best. It is machined from high-quality 7075-T6 aluminum and holds capacitors with a diameter of up to 15mm.

The large surface for both the capacitor and the chassis mounting area provides secure fastening without having to worry about losing the capacitor. Small dimensions allow easy mounting, even in crowded 1/10 scale touring cars. The Ultra Cap Catcher is best used with larger diameter capacitors but also works just perfect with smaller caps thanks to the crescent-shaped design. Plus, when the cap is installed with heat-conductive tape the black anodized mount also acts as a heat sink.
